Tug light electric switches, with a shape similar to the u type, with their launchers and receivers installed in the same u shell. Because of the lack of calibration at the time of installation, the ease of connection and the high value of the value of the service, it is highly favoured by engineers in mechanical design. The birgafo microtrain pv series consists of the gl2 series, the gl3 series with no built-in amplifiers and the gl5 series with built-in amplifiers. Today, let's see how the series is different. How does it work? How do we detect when the product fails?
Rationale
Usually, the pv of the slot you see on the market may be:
The pv internal structure of the unincorporated amplifier tank consists of the luminous diodes and the photo-sensitive triodes, as illustrated below. When a telecommunications signal is sent into the input end of the sensor, the luminous diode sends infrared light through the current, the light-sensitive tripolar tube is luminous and produces the current, ce-guided; when the input end is not signaled, the luminous diode is not bright, the luminous triode is closed and the ce is not functional。
Test method
The use of gl2/gl3 requires the customer to design the outer circuit and does not allow direct access to electricity. If it is to be judged as good or bad, simple tests can be performed using a spare table diode:
(1) the red pen (+) to the a, black pen (-) to the k-end allows the detection of the conductive voltage; the counter is transposed to show infinite magnitude. Both positive and reverse electrical resistance are infinity。
(2) better detection methods are used to test access to power and resistance, typically by connecting to:
In typical detection circuits, light-sensitive output signals are unstable and are analogue signals. To export a more stable signal, external circuits, such as a connector to the voltage comparator, are required to perform an a/d conversion to output a stable voltage value。
The configuration of a gl3-based circuit to pull up resistance and remove treatment circuits becomes gl5. The gl5 product incorporates magnification circuits that can be connected directly to standard sensors, such as the di port that accesss plc。
Typical application
Line model groups, which are already widely used in optical-voltaic devices, feed mechanics, tailoring equipment, rubber coating equipment, stickers, etc., allow for more flexible load movements and accurate positioning of the multiple axes. Typically, there are three slot switches installed on a single module to achieve the left limit, the original location, and the right limit。
In rotational institutions, micro-train switches are economically viable solutions that allow for the detection of gear speeds and step control of flipping institutions。
A bright spot on the edge
The receiver and launcher are integrated and occupy small space
Cost advantage, high value for money
High accuracy of positioning
Use infrared light, not influenced by dust
